IMPROVEMENT IN SOLDERlN-G'APPARATUS.

^ Specification forming part of Letters Patent No. 88,410, dated March30, 1869.

To all 'whom 'it may concern:

Beit known that we, CHARLES PRATT, of the city, county, and State of NewYork, and CON- RAD SEIMEL, of Green Point, Kings county, New York, haveinvented a new and Improved Soldering Apparatus; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure l represents a plan or top View ofour improved soldering-pan. Fig. 2 is a vertical transverse section ofthe same, taken on the plane of the line Fig. 1. Fig. 3 is a verticallongitudinal section ofthe same, taken on the plane of the line y y,Fig. l.

Similar letters of reference indicate corresponding parts.

This invention relates to anP apparatus intended for holding sheet-metalvessels and cans vwhich are to be soldered at their edges, the parts ofsuch apparatus holding the same being made adjustable, so that the canor vessel can be immersed in the solder to the requisite depth, and beraised out, when soldered, in a straight line, thus preventing theunequal distribution ot solder occasioned by careless handling.

The invention consists, chiey, in retaining the can or box to besoldered in a proper position by means of a frame, which can bedepressed and elevated at will, to allow of the can or box beingimmersed in and raised out of the solder uniformly to the requiredextent.

The invention consists, also, in the application of a base-piece, beingattached to and having thesame motion as the frame which serves toprotect the bottom of the can to be soldered, so that it cannot bereached by solder; also to sustain the can it' the frame should bedispensed with. l

A in thev drawing represents a solderingpan of ordinary construction.From the sides of the pan project two or more guideposts, B B, which maybe hollow, as shown, or solid. They serve as guides for the verticalarms a of a frame, G, which frame consists, chley, of a top plate, b, asshown in Fig. 1, and of the arms a. From the frame C there is suspendedabove the soldering-pan, by means of rods c, a base-piece, D, which hasits edges somewhat turned np, as shown in Figs. 2 and 3.

The can to be soldered is placed upon the base-piece D, as in Fig. 2,and its bottomprojects beyond the sides of said base-piece, so that whenthe base-piece is lowered into or toward the solder, the edges of thecan Will be immersed in solder to the requisite depth.

The upward-turned edges of the base-piece protect the bottom of the canand prevent its being reached by the solder.

The base-piece D, instead of being suspended from the frame C, can asWell be supported on an adjustable stem, .or on other equivalentapparatus, by which it will be rendered adjustable in a verticaldirection.

The frame C, when used, may be arranged without a base-piece, D, forsome kinds of cans, especially where the same may be suspended, by meansof their upper projecting ilan ges, d, from the plate b, as indicated inFig. 2. Where the cans have not got these projecting anges, theadjustable base-piece is indispensable to sustain the bottom of the can.

The apparatus for depressing and elevating the frame C, or thebase-piece D, or both, may be varied, and may be connected with atreadle, screw, vor other suitable convenient device, without changingthe distinctive features of our invention.

It is well known that it is important in dipping cans to have themperfectly true, so that all edges are dipped at the same time into themolten solder, and to the same depth.

It is also important that the can, when soldered, should be immediatelyremoved in a perfectly upright direction from the molten solder, so thatsome of its sides will not receive more solder than others by improperhandling.

With our improved frame or base-plate, or both, the process of solderingcans can be carried on iu a perfectly true and reliable man- 11er, andat a small expense, and unskilled hands need only be employed to operateit.

By having the can adjustable over a xed and open pan, the latter maycontain a larger quantity of solder, which can consequently be morereadily kept at a uniform temperature than the small quantities used inmovable for sustaining the can, substantially as depans. scribed.
